Apple Watch series 2 draining battery during night while on table?

So, I have a series 2, and Ive noticed it drains battery while on my nightstand, while I am asleep. Its not in use obviously. I have noticed, the slightest tap on my bedside table, just on the table itself, causes the watch to light up.

Is there a way to reduce or eliminate this from happening?

I plug in my phone before bed as well as my watch. But take both off the charger before I actually sleep. When I wake up, my phone is usually still at 100 percent or close to it. My watch sometimes falls below 90.

This seems odd. My battery for the watch otherwise is good to excellent. Ive had the watch several weeks and I've gone all day without having to recharge it during the afternoon, so the battery is amazing.

But still Id like to start my day with 99-100 percent battery as opposed to 89-90.

Whats going on here?

i think the Watch is just sensing movement, as it is designed to do, when not on charger. Is there a reason you can't or won't just leave it in the charger? I feel that is what Apple had in mind when designing the device.

You can turn off nightstand mode in the settings.

Also, don't unplug them, let it stay on the charger overnight so it's not wasting charge communicating back and forth with your phone. Just because you're not using it doesn't mean it's not doing anything.

Agreed your iPhone and Apple Watch are some how draining power during the communication between the two.

The :apple:Watch radios are on and working (talking to iPhone and WiFi).The small battery means this will be a meaningful drain even when not using.

The most effective way yo start your day at 100% is to do what most do and leave it on the charger overnight. Then you have 100% every morning.

I used mine all day yesterday and with 75% left at bed time I decided not to charge it last night, woke up to 68% this morning so a 7% drop over night. S2, 42mm, screen brightness set to high. The battery was a concern since mine is off charge 15 hours a day but thank goodness no problems.

This is okay to do? Whether its my phone or watch, I usually just let it charge before bed, then take the charger off when it gets to 100, before I sleep. Both take relatively quick to charge, so having both charge for 8 hours, while I am not using them, sounds counter productive.

Last night my Watch battery dropped by about 20% and the iPhone was in airplane mode so they were not exchanging data.
Wi-fi is always on so maybe Watch was fetching data from the internet, but one night I left the Watch unplugged in airplane mode and it dropped by about 10% and of course it wasn't doing network activity.
The best advice is to leave it charging during the night so it is 100% when you wear it and start your day.

It's perfectly fine to leave the watch and the iPhone connected to power all night. The batteries will only charge until they are full then the charging circuit shuts off and they are simply connected to power and any things they are doing in the background will simply run from the electrical source not the battery, the same as any other electrical device.

Why do some of you take your devices off the charger at 100%? The charge logic is designed to not damage the battery when it's fully charged and when you take it off it begins another discharge cycle and degradation of the battery life.

Also if the device is to be stored for a length of time I believe the recommended charge level before turning them off is around 50% for optimum battery life.

BTW this applies to all the newer Apple devices which have batteries, not just iPhone and watch.

Your phone is still at 100 percent after a night off the charger? You must have the best battery in the world.
